THE CONNECTION BETWEEN ROUTER AND INMARSAT B
SIGNAL ROUTER D-SUB9 INMARSAT
B
D-SUB 25PIN
CARRIER DETECT 5 1
RECEIVER DATA 3 2
TRANSMIT DATA 2 3
DATA TERMINAL READY 20 4
SIGNAL GROUND 7 5
DATA SET READY 6 6
NOT CONNECTED 7
RECEIVER CLOCK 17 8
TRANSMIT CLOCK 15 9
SHORT PIN 6-8
NOTE :V25bis DOES NOT INCLUDE THE USE OF CARRIER DETEC
THEREFOR THE CABLE NEEDS TO BE SHORT-CIRCUIT AT THE
FTE SIDE BETWEEN PIN NUMBER 6(DSR) AND PIN NUMBER
8(DCD)
TO CONFIGURE SAT B TERMINAL FOR HSD WE USE SERVICE PC
AND SET IT FOR V25BIS DAILING AND WHEN WE SET V25BIS
THE CLOCK RATE ON THE BTERMINAL WILL AUTOMATICALLY BE
SET TO 64KBPS
WE HAVE USE NAME ANDPASSWORD AND THE DAILING NUMBER TO
LAND EARTH STATION IS 28# AND WE HAVE ONLY DNS SERVER
ie ( 194.151.62.49).
HOW TO CONFIGURE THE ROUTER 1720 SUCH THAT DTR
BECOMES HIGHT AND IT DAIL THE HSD MODEM OF SAT B
TERMINAL AND GET CONNECTED TO ISP OF LANDEARTH
STATION .

seem to remember that this technique can take a while, so need a long
wait-for-carrier-time, also the trick is to get the interface in an up/up
(spoofing) state using sh int ser0/0, otherwise it doesn't raise DTR with
traffic

Hello!!
Thanks for Reply regarding the Router config. for
sych. Dial-up mode for 64 kbps High speed data.
I tried configuring as per info. given by u.
Still not able to dial.
I am forwarding u the configuration which i did.
When i checked the status of Serial s0, it showed me
seril 0 =up & Line =up. But DCD=Down
I configured modem to Synch. with "AT&M1" Command.
for testing.
I am not able to Dial , Status Led shown on modem
after configuring was :
Pwr,MR,DTR= High

Note : I am confused why this not happened, since
serial S0 was showing me UP. I was also able to ping
the IP of mapped address. of 203.124.230.36 [server]

if u use cisco configmaker to set up a serial connection with modem, u will
see the control strings needed regarding to different modems. one of the
string (s0=1) is used for auto answering. i don't know ur application, but
at least the server router should be auto answering.
when i say hub, i mean the lan side of the router has to be connected with
something. normally i use hub. but i guess pc is ok.

hello ......
thanks for ur rply .regarding configmaker i found
one problem is that how can u use or set for sync
modem . becoz i dont find any option for sync modem
for (v25bis), what i find is dail in pc modem. is
there any new upgradation for the same, where i can
enter sync modem . if this is possible well my problem
will be solved for configuration.i am trying to search
for latest ver of configmaker .if possible to
download too.
modem 1720 serial sync.....dail in pc modem
(available in configmaker).
if possible if i get .
router1720 sync serial .....sync modem v25bis.
it will be fine.
with warm and best regards

Hello, What is the Manufacturer and the Model of your modem. If I have
that info I can make a modemcap for you.

Thanks
Mike
